Final answer:
The quotients of the expressions 12/(-6) and -15/(-3) are -2 and 5, respectively.
Step-by-step explanation:
To find the quotients of these expressions, we divide the numerator by the denominator. Let's look at the first expression, 12/(-6). Dividing 12 by -6 gives us -2. So, -2 represents the quotient of 12/(-6).
Now, let's look at the second expression, -15/(-3). Dividing -15 by -3 gives us 5. So, 5 represents the quotient of -15/(-3).
Therefore, the points on the number line that represent the quotients of the expressions are -2 and 5.
